To calculate the work done by the person lifting the bowling ball, we can use the formula for work:
\[ \text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta) \]
In this case, the angle \(\theta\) is 0 degrees because the force is applied in the same direction as the movement (upward). Therefore, \(\cos(0) = 1\).
Given:
- Force = 60 newtons
- Distance = 2 meters
Plugging in the values:
\[ \text{Work} = 60 , \text{N} \times 2 , \text{m} \times 1 \] \[ \text{Work} = 120 , \text{joules} \]
So, the person did 120 joules of work.
The correct response is: 120 joules.
